推荐答案

可能不是你想要听到的答案，但是这个功能不支持AWS的Java SDK。你只可以生成pre-签署网址获取或放置一个对象。

Probably not the answer you want to hear, but this functionality isn't supported in the AWS SDK for Java. You can only generate pre-signed URLs to get or put an object.

在原则上，你可以pre-签署任何操作，但它变得复杂快。例如，复制对象操作需要必须签署特定的头文件，所以pre-签署URL和服务，最终访问该网址也都需要同意这些头的时间提前。

In principle you can pre-sign any operation, but it gets complicated fast. For example, the copy object operation needs specific headers which must be signed, so the pre-signed URL and the service eventually accessing that URL would both need to agree on these headers ahead of time.
